Abstract: The present invention relates to a picking arm which may be displaced along a stationary longitudinal guide. A picking head for electrical components may be displaced along a transverse guide on the picking arm by a linear motor. A support for the picking arm embodied as a box-like hollow body is made from plastic reinforced with carbon fiber. The transverse guide and a stator for the linear motor are arranged on a lateral wall of the support. The lateral wall is reinforced by reinforcing elements against local deformations which are caused by the magnetic forces of the linear motor.

Abstract: The present invention is directed to a coil unit of a single-acting linear engine. The coil unit includes an iron core with coils that are linked with the iron core by way of a cast compound thereby forming a molded part. The molded part is enclosed by a housing having a narrow circumferential gap formed between the housing and the molded part. Through the gap, cooling air may flow or be blasted. The air extensively cools the iron core with the coils and thermally insulates the housing from the iron core and the coils.

Abstract: The invention relates to an insertion head 10 with a drive shaft 2 bearing a mechanism 5 for gripping a component 7, whereby said shaft is capable of being driven by a drive motor 1. The drive shaft 2 is directly formed by the hollow output shaft of the drive motor 1.

Abstract: The invention relates to a device for interchanging suction pipettes which can be removed from a magazine and coupled to a fitting head of a fitting device and detached from the fitting head and deposited in the magazine. The fitting head has, on its side facing the magazine, a motor on whose driven shaft a star-shaped part and a latching plate are mounted. The latching plate has at least one nub (121) which, after insertion of the star-shaped part into a star-shaped cutout in the suction pipette held in the magazine and after rotation of the star-shaped part and the latching plate into a locking position, engages in a notch, and which, on insertion of a suction pipette held on the star-shaped part into the magazine, can be moved out of the notch.

Abstract: A sorting apparatus is provided which includes a plurality of article carriers which circulate on a conveying device. The article carriers are capable of discharging the articles in a controllable manner. Each article carrier includes a fixed wall and a movable wall. The movable wall forms, in a closed position, together with the fixed wall, a receiving pocket for the articles. The movable wall also forms, in a discharge position, together with the fixed wall, an injection slit which is open at the bottom of the pocket and which is intended to convey the articles downward through an injection chute formed by the movable wall. The movable wall engages a support structure such as a plurality of rollers or wheels for conveying the articles. The movable wall may also include a slit for receiving a distal end of the fixed wall to the two walls together in the closed position.
